I didn't finished it yet so now it can looks crapy.

Earth with moon and sun.
All of these things have gravity on it.
Earth have normal gravity (like on earth).
Moon have realistic (i think) moon gravity.
Sun have more powerfull gravity.
Oh and also everything what collide with sun just dissappear.

To test gravitys just make something (box, circle, polygon) and drag it from earth to sun, moon etc.

P.S. Sorry for my english ^^

EDIT: Update

EDIT2: I want upgrade it and blah blah blah... I made it because i was bored so i won't finish it. Blah blah blah...
